Question

PowerPoint to pdf -- loss of image quality (samples provided)

Hi there. We hope we can get some competent help. We tried to solve this for the past couple of hours, but no luck.

 

We have a PPT PowerPoint file (MS Office 2007) which includes a couple of screenshots and other images, all in excellent/sufficient quality, but once we try to save the file as a PDF, the image quality decreases dramatically.

 

Please note, we tried both the PowerPoint 'print as pdf' function, as well as converting the PPT directly in/through Adobe Acrobat. Same result. We played with the compression options, trying to minimize or even entirely switch off compression, no luck. We did some (safe) registry changes for PowerPoint, as suggested in other boards, also no luck. We tried many different pdf converters (not only Acrobat), nothing.

 

Here's the picture quality in PowerPoint: http://ibin.co/2JfaGNGXCiXd

Picture quality in the generated pdf: http://ibin.co/2JfaNF8Br5OQ

Direct comparison PPT-->PDF: http://ibin.co/2JfaRImLmXaw

What are we doing wrong?

 

Thank you for your help!!

    Hello. The latest update to the MS Office site fixed this absurd bug. I was experiencing the same problem described above before the fix but after the latest updates, PDFs are again looking as they should (when quality is set to "High" in PPT). For details on the latest PPT update –16.15 (Build 180612)– please  see here:

    What is the ppi (pixels per inch) of your images? Were they resized after putting them into PowerPoint? Bigger or smaller? What software did you use to take the screenshots? Where did the other images come from? Did you copy them in or insert them?

    When you make the PDF, do you use the Acrobat tab in PowerPoint?

      same issue, tried the fix with no luck. Have been re-screen shot-ing the needed images again that I used in the PPT and am pasting them into the PDF version... not fun

      Hi ste14978294,

      Please let me know the exact dot version of Acrobat installed on your computer?

      Try the below settings : -

      Open Acrobat, navigate to Edit menu -> Preferences -> Convert to PDF categories -> Microsoft Power Point -> Edit Settings -> Adobe PDF Settings : High Quality Print.

      Click Ok to confirm the changes.
